Where are proteins synthesised inside the cell

India – which part of the cell is called a protein factory which part of the cell is called a protein factory– We are going to start the discussion about WHICH PART OF THE CELL IS CALLED A PROTEIN FACTORY as per our readers’ demands and comments. If you want to know about this India topic, continue reading and learn more. People Also Read: Refer: A diagram representing the cell as a factory. The cell membrane is represented as the. The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplam.

\( \newcommand\) • • • • • • Each polypeptide protein translated by ribosomes from a sequence of bases in an mRNA has a specific functional location, either in the cytoplasm, on cellular membranes, inside organelles or in extracellular fluids. In this section we consider the movement and sorting of proteins in the endomembrane system as well as the transport of proteins into and out of organelles A. Packaging Proteins in the RER All protein synthesis begins in the same way, with the formation of an initiation complex and subsequent elongation cycles peptide bond formation and carboxylterminal amino acid addition. However, secretory proteins and those destined for lysosomes, peroxisomes or other microbodies, complete elongation directly into cisternae, or spaces enclosed by the rough endoplasmic reticulum ( RER). It is possible to isolate and purify proteins secreted by cultured cells. A good model system for studying secretory protein synthesis turn out to be mouse myeloma cells. Mouse myeloma cells were isolated and grown in culture, where they synthesize an IgG light chain, a polypeptide that is part of a mouse immunoglobulin molecule. Immunoglobulins are assembled from light and heavy chain polypeptides and secreted into the circulation. There they serve as circulating antibodies of the vertebrate immune system. Mouse myeloma cells are cancer cells that have lost the ability to make the heavy chain polypeptides. Instead, they secrete mostly the IgG light chain, making i...
